Hidden Expedition: Dawn of Prosperity 2015-10-06

Hello, Agent! We have another strange case for you. We've detected an unusual signal coming from the vicinity of an old weather station. Strange quakes have been detected there, though the area isn't an active earthquake zone. The nearby observatory is also showing signs of activity after years of being abandoned. We suspect something big – and possibly sinister – is happening there. Track down the signal and find out the truth!
